DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0019] like Figures 1 to 3 As shown, a collecting device for a paper cup forming machine of the present embodiment comprises a frame 1, wherein the frame 1 is provided with a cup collecting frame 2, a cup feeding mechanism 3 for pushing paper cups from below to the cup collecting frame 2, and a manipulator 4 for transferring paper cups stacked on the cup collecting frame 2; the cup collecting frame 2 comprises a cup collecting ring 21 fixed to the frame 1, the cup collecting ring 21 is provided with an inner clamping piece 22 for preventing paper cups from falling and an outer clamping piece 23 for preventing stacked paper cups from tipping over, the inner clamping piece 22 and the outer clamping piece 23 are both spring sheets, the lower ends of the inner clamping piece 22 and the outer clamping piece 23 are both fixed to the cup collecting ring 21, the inner clamping piece 22 is bent toward the center of the cup collecting ring 21, and the upper section of the inner clamping piece 22 is vertical or bent into an arc with a convex surface facing the center of the cup collecting ring 21.

[0020] This embodiment is installed at the cup outlet of the paperboard forming machine, and is used for stacking, collecting and transferring paper cups. The cup delivery mechanism 3 includes a turntable 31 that receives paperboard from the paperboard forming machine and can rotate horizontally. The turntable 31 has three circular holes 32 for clamping paper cups evenly distributed in the circumference. The turntable 31 rotates quantitatively at intervals, and one of the circular holes 32 is always located directly below the cup collecting ring 21. A top plate 33 is provided below the turntable 31 to push the paper cup from the turntable 31 to the cup collecting rack 2. During operation, the formed paper cup falls to the circular hole 32 of the turntable 31, and then the turntable 31 rotates 120° so that the paper cup is located directly below the cup collecting ring 21. Then the top plate 33 is raised to push the paper cup to the cup collecting rack 2, so that the four sides of the paper cup are clamped by the inner clamping piece 22 to prevent it from falling. Repeat this action, and the lower paper cup is covered with a paper cup, so that the paper cups are stacked and continuously rise.

[0021] The height of the outer clip 23 is adapted to the height of the paper cups to be stacked. When the paperboards are stacked to a certain height and block the infrared rays set on the outside, the infrared detector will send a signal to the robot 4, and the robot 4 will transfer the stacked paper cups from the cup collection rack 2 to other places according to the preset process.

[0022] To complete this action, the manipulator 4 includes a slide rail 41 fixed to the frame 1. A slider 42 is slidably connected to the slide rail 41. The frame 1 is provided with a first cylinder 43 for driving the slider 42 to move horizontally. Two vertical slide bars 44 are slidably connected to the slider 43. The bottom of the slide bar 44 is fixed with a "U"-shaped mounting plate 45. The slider 42 is provided with a second cylinder 46 for driving the mounting plate 45 to move up and down. The front forks of the mounting plate 45 are located on both sides of the cup receiving ring 21 and are provided with a third cylinder 47. The front ends of the piston rods of the two third cylinders 47 are provided with clamping plates 48 for clamping paper cups.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention. For the convenience of describing the technical solutions, the front, back, left, right, up, middle, down, etc. directions used are based on the drawings and are not limitations on the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
